Abstract (en)
[origin: ES274220U] An electrically driven appliance such as a citrus press comprises a drivable tool a self-starting single-phase synchronous motor including a diametrically magnetized permanent-magnet rotor forming a rotor field and positioned between two stator poles forming a stator field and a drive mechanism arranged between the motor and the tool, for driving the latter, such mechanism including a plurality of drive elements each engaging the adjacent element or elements. A stalling device coacts with one drive element having a pair of stops, the stalling device including a member alternately engageable with such stops after a specific number of revolutions of the rotor in either direction of rotation, such engagement effecting stalling of the rotor and automatic reversal of the direction of the rotation of the rotor. The physical relationship of the stalling device member and the stops to each other is such that the rotor is stalled in positions wherein the angle between the rotor-field vector intersecting the rotor axis and a line intersecting the rotor axis perpendicularly to the stator field lies within an angular range of 60 DEG in each direction of rotation of the rotor.
